Your job requires that you have a rugged, reliable and accurate digital multimeter. The Fluke 17B+ digital multimeter does all that and more. Common basic electrical measurements plus temperature, frequency and duty cycle. Easy to use with one hand, even with gloves on, the Fluke 17B+ offers everything you need.

Accuracy Specifications

Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to 28 °C, relative humidity at 0% to 75%. Accuracy specifications take the form of: ±(% of Reading + Number of Least Significant Digits).

1All ac, Hz, and duty cycle are specified from 1% to 100% of range. Inputs below 1% of range are not specified.2Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA.3Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range).4Typical means when the frequency is at 50 Hz or 60 Hz and the duty cycle is between 10% and 90%.
